SACRAMENTO (CBS/AP) — Kern County is the latest Central Valley government to sue the state over its $68 billion bullet train plan.

Officials say they filed suit Friday in Sacramento County Superior Court over the environmental review for the Fresno to Bakersfield section approved last month.

County Counsel Theresa Goldner says the 20,000-page review is incomplete. She says it includes designs for only 15 to 30 percent of the 114-mile corridor and that officials failed to consider things such as relocating electrical infrastructure and access to Bakersfield parkways.

High-speed rail spokeswoman Lisa Marie Alley says the agency chose the route based on requests from Kern County. She says the environmental review “was thorough and complete” and possibly the most comprehensive in California history.
